![]() ![]() (Note:Since the connector is reversible/flippable as with the magsafe connectors, upper and lower rows are interchangeable as you have stated already. (let me try to visualise the prolongued o-shaped connector by text only) Your post here, however, has been of great help.Įxtensive reading combined with my own measurements, and guided by your above post, show the following: Having recently acquired a possibly broken ACD 20"without a power brick, I have been desperately trying to find the power connector pinout. (drop resistor may bridge the upper and lower center) they're really charred up. It appears to be a top and bottom row of 5 pins each, speculating the top and bottom of each row are common, plus the leftmost and rightmost common and the next left and next right also common. Having cracked the nut open, it's merely two power wired (+24.5v DC) plus a drop resistor for one of the pins (60kOhm) probably to identify the pack to the display. It may not be too difficult to figure out the wire mapping, I'm just posting this request now in advance in case I need the information. I haven't gotten the pack cracked open yet, it's a bit of a chestnut if you know what I mean. I'd much rather just fix this one, I don't care about cosmetic condition when I'm done so long as it works. Probably involves finding someone with one with a busted LCD panel on ebay that can provide the entire display with cable and brick. Costly and a lot of work compared to my plan. The only other way to fix it is to find a new brick and a display I can salvage the cable from, and figure out how to take it apart. From what little I've been able to find on it, the display's white LED should flash a warning if the wrong pack is attached, leading me to believe it has a method similar to the magsafe for standard communications and negotiates between the brick and the display before sending power. The connector is not keyed and can be plugged in 180deg and work the same. There are several things that use that same shape connector, including all the cinema displays and mac minis. I'm having problems finding a pinout for the connector. (or depending on the number of contacts needed, I may use a 4 pin molex like what's used on 3.5" IDE HDDs) I'd like to take the pack apart and hard-wire it to the display. I have here an apple 30" cinema display and power brick, where the connector between the brick and the display cabling is badly damaged on both sides by arcing. ![]()
